64COPY is an all-purpose DOS and C64 emulator file manager, modelled after Norton Commander, and runs under the Windows DOS VDM (32-bit or lower), and in real DOS. The 64-bit editions of Windows have no DOS VDM, so you will need to install a DOS-like emulator like DOSBox. It specializes in converting and manipulating emulator files between various formats, as well as a very flexible 6502 disassembler. 64COPY does not do any communication to the 1541/71/81 floppy drives to read disks. If that is what you need, download Star Commander for that task.
